FIELD

This disclosure generally relates to flashing mounting systems forroof-mounted photovoltaic arrays and, more specifically, to flashingassemblies including flashing and tape.

BACKGROUND

Photovoltaic (PV) modules may be mounted to a surface of a structuresuch as a roof to form PV arrays. Each PV module may be mounted to thesurface by mounts that secure the PV module to the surface and elevatethe PV module above the surface. For example, the mounts may includehooks and/or stanchions. Sometimes, securing each mount to the surfacecauses one or more penetrations in the surface. Typically, photovoltaicarrays require numerous mounts and, thus, numerous penetrations in thesurface. However, such penetrations may need to be sealed to preventwater intrusion into the structure through the penetrations.Accordingly, flashing may be positioned on the mounts and over eachpenetration. The interface of the flashing and the surface may be sealedusing sealant materials. For example, flashing on roofs may be sealed byapplying a viscous roofing sealant and layers of mesh materials.However, such sealant materials increase the cost and time required tomount the PV modules. In addition, the flashing may be improperly sealeddue to installer error and/or use of improper materials.

Accordingly, there is a need for a system that simplifies the process tomount photovoltaic arrays and reduces the opportunities for impropersealing of any penetrations in a surface.

DETAILED DESCRIPTION

FIG. 1 is a sectional view of a system 100 for mounting photovoltaic(PV) modules 101 on a surface 102 of a structure. The structure may be,for example, a building having a sloped or flat roof or any otherstructure suitable for mounting PV modules. The system 100 includes amount 104 and a flashing assembly 106. In the example, the mount 104includes a hook for use with roof tiles. The mount 104 is placed againstan underlayment of the surface 102 such as roof felt such that the mountextends underneath roof tiles. A portion of the surface 102, such as oneor more tiles 108, may be removed to provide access to the underlaymentof the surface. Fasteners 110 are secured through the mount 104 and intothe structure. In other embodiments, the mount 104 may be secured to thesurface 102 using, for example, fasteners, adhesives, and/or any otherattachment means.

As an example, embodiments of the systems and methods are described inthe context of PV modules. However, the flashing assemblies 106 may beused to flash any penetrations in surfaces. For example, the describedembodiments may be used for penetrations in roofs such as penetrationsfor heating, venting, and air-conditioning systems, plumbing vents,chimneys, mechanical attachments, and any other components requiringpenetrations in roofs. The term “penetration” refers to an opening in asurface.

The flashing assembly 106 may be positioned over a portion of the mount104 and over any openings in the surface 102. As described furtherbelow, the flashing assembly 106 includes tape to provide a watertightseal around the flashing assembly. Accordingly, the time required tomount the PV modules 101 is greatly reduced. For example, the total timeto install the PV modules may be reduced by as much as 24 hours incomparison to systems that require time for sealant materials to dry orcure. The time required for an installer at each mount 104 may bereduced by as much as 95%. Moreover, the flashing assembly 106 reducesthe opportunity for incorrect installation of the flashing assembly.Also, the flashing assembly 106 reduces waste of materials duringinstallation of the PV modules.

When the mount 104 is secured to the surface 102, any removed portionsof the surface may be replaced and the PV module 101 may be attached tothe mount 104. For example, a bracket 112 may be attached to the mount104 and a rail 114 attached to the bracket. One or more PV modules 101may be attached to each rail 114. In other embodiments, the PV modules101 may be mounted in any manner that enables the PV module 101 tofunction as described. For example, the PV module 101 and/or the rail114 may be directly attached to the bracket 112 and/or the mount 104. Inaddition, each PV module 101 may be attached directly or indirectly to aplurality of mounts 104.

In the example, the mount 104 includes a hook. In other embodiments, thesystem 100 may include any mount 104 that enables the system to functionas described. For example, in some embodiments, the mount 104 mayinclude a stanchion 174 (shown in FIG. 22) that secures to the surface102 and elevates the PV module above the surface. The footprint and thepost of the mount 104 may be rectangular, square, circular, triangular,and/or any other suitable shape.

FIGS. 2-5 show a flashing assembly 106 for use with the system 100.Flashing assembly 106 includes flashing 118 and tape 120. Flashing 118is sized and shaped to extend across an interface of the mount 104(shown in FIG. 1) and the surface 102 (shown in FIG. 1). In the example,the flashing 118 includes a sloped or first portion 122 and a secondportion 124. The first portion 122 is configured to receive and extendacross a portion of the mount 104 (shown in FIG. 1). The second portion124 is configured to extend along the surface 102 (shown in FIG. 1). Inthe illustrated embodiment, the first portion 122 is non-planar orsloped and the second portion 124 is planar. In other embodiments, theflashing 118 may include any portions that enable the flashing assembly106 to function as described.

In addition, the flashing 118 includes a bottom surface 126, a topsurface 128, and an edge 132 extending between the top surface and thebottom surface. The bottom surface 126 contacts the surface 102 (shownin FIG. 1) when the flashing 118 is installed on the surface. Theflashing 118 may be constructed of metal, plastic, and/or any othermaterial that enables the flashing to function as described. In otherembodiments, the flashing assembly 106 may include any flashing 118 thatenables the flashing assembly to function as described.

In reference to FIGS. 3-5, in this embodiment, the tape 120 includes atop surface 133, a bottom surface 134, a first attachment area 136, anda second attachment area 138 (shown in FIG. 6). The tape 120 includesoverlapping strips 148, 150, 152. In this embodiment, the tape 120includes three rectangular strips 148, 150, 152. The tape 120 ispositioned on the top surface 128 of the flashing 118 and extends overthe edge 132. Moreover, the strips 148, 150, 152 overlap each other.Such an overlapping configuration may prevent water from penetratingthrough the flashing assembly 106. In other embodiments, the tape 120may have any configuration that enables the flashing assembly 106 tofunction as described. For example, in some embodiments, the tape 120may include a single continuous strip attached to the flashing 118. Infurther embodiments, the tape 120 may be attached to the bottom surface126 (shown in FIG. 11) of the flashing 118.

The flashing assembly 106 has a first configuration and a secondconfiguration. In the first configuration, the first attachment area 136of the tape 120 is attached to the flashing 118 and the secondattachment area 138 (shown in FIG. 6) is unattached. In addition, thetape 120 may be positionable in the first configuration to facilitatepositioning the flashing assembly 106 relative to the surface 102 (shownin FIG. 1). In the second configuration, the second attachment area 138(shown in FIG. 6) may be attached to the surface 102 (shown in FIG. 1)such that the tape 120 extends across an interface between the flashing118 and the surface. Accordingly, the flashing assembly 106 facilitatesflashing the mount 104 (shown in FIG. 1) of the PV module 101 and thesurface 102. In particular, the flashing assembly 106 includes allcomponents required to seal penetrations from the mount 104 (shown inFIG. 1) being secured to the surface 102 (shown in FIG. 1).

The term “tape” refers to a material that is configured to stick to asurface when the material contacts the surface. For example, the tape120 may include an adhesive on the attachment areas 136, 138 (shown inFIGS. 3 and 6) configured to attach to the mount 104 and/or the surface102 (shown in FIG. 1). In addition, the tape may be designed to sealasphalt, rubber, modified bitumen roofing underlayments, roofingmembranes such as TPO (thermoplastic polyefin), EPDM (ethylene propylenediene terpolymer), PVC (polyvinyl chloride), and/or any other surface.In other embodiments, the flashing assembly 106 may include any tape 120that enables the flashing assembly 106 to function as described. In someembodiments, the tape 120 includes a single, continuous strip attachedto the flashing 118.

In reference to FIGS. 3 and 6, the flashing assembly 106 also includes afirst release sheet 140 and a second release sheet 142. The firstrelease sheet 140 may be positioned on the first attachment area 136 andthe second release sheet 142 may be positioned on the second attachmentarea 138. The first release sheet 140 may be removed from the firstattachment area 136 to allow the first attachment area to attach to theflashing 118 and form the flashing assembly 106. The second releasesheet 142 may remain over the second attachment area 138 to preventobjects attaching to the second attachment area when the flashingassembly 106 is in the first configuration. In this embodiment, eachrelease sheet 140, 142 may comprise a plastic or non-adhesive sheet thatcovers the first attachment area 136 and/or the second attachment area138. In some embodiments, the release sheet 140, 142 may include a gripto facilitate removal of the release sheet 140, 142. For example, therelease sheet 140, 142 may be oversized relative to the respectiveattachment area 136, 138 such that a portion of the release sheet isexposed for a user to grasp. In other embodiments, the flashing assembly106 may include any release sheet 140, 142 that enables the flashingassembly to function as described. For example, in some embodiments, thesecond release sheet 140 is larger than the second attachment area 138and is sized and shaped to be positioned between flashing assemblies 106when the flashing assemblies are stacked. In further embodiments, theflashing assembly includes a third release sheet.

As shown in FIGS. 6 and 7, the second release sheet 142 may be removedfrom the second attachment area 138 to allow the second attachment areato attach to the surface 102. The flashing assembly 106 switches fromthe first configuration to the second configuration when the secondattachment area 138 is attached to the surface 102. Thus, the secondrelease sheet 142 inhibits improper attachment of the second attachmentarea 138 and allows the flashing assembly 106 to be accuratelypositioned relative to the surface 102. Moreover, the flashing assembly106 simplifies sealing of the system 100 because the flashing assembly106 is easily switched from the first configuration (shown in FIGS. 4and 5) to the second configuration (shown in FIG. 7). On a sloped roof,the flashing assembly 106 and the surface 102 form a watertight sealwhen the flashing assembly 106 is in the second configuration. In otherembodiments, the flashing assembly 106 may be attached to the surface102 and/or the mount 104 in any manner that enables the flashingassembly 106 to function as described.

Referring again to FIGS. 3 and 6, in some embodiments, substantially theentire bottom surface 134 and/or top surface 133 may include an adhesivedefining the first attachment area 136 and the second attachment area138. In such embodiments, the first attachment area 136 and the secondattachment area 138 may be adjacent and the first release sheet 140and/or the second release sheet 142 may be cut to allow selectiveexposure of the first attachment area and the second attachment area. Inthis embodiment, the first release sheet 140 and the second releasesheet 142 are precut such that each release sheet is sized to fit therespective attachment area 136, 138. Each release sheet 140, 142 may beremoved as a separate piece. In other embodiments, at least one of therelease sheets 140, 142 may be omitted. For example, in someembodiments, the flashing assembly 106 may include a single releasesheet. In further embodiments, the flashing 118 and/or the tape 120 maybe configured to prevent the second attachment area 138 from attachingto the flashing 118. Accordingly, in such embodiments, the secondrelease sheet 142 may be omitted or removed in the first configurationbecause the flashing assemblies 106 may be stacked without the secondattachment area 138 attaching to the flashing 118.

In reference to FIG. 7, the flashing assembly 106 may be attached to thesurface 102 and positioned to inhibit water penetration through thesurface. In particular, the flashing assembly 106 may be positionedrelative to a slope of the surface 102 such that a direction of liquidflow 144 is away from any openings, potential weak points or joints inthe flashing assembly. For example, the flashing 118 may be positionedsuch that the sloped portion 122 slopes away from the surface 102 alonga direction of liquid flow 144. In addition, the overlapping tape 120may be configured such that the liquid 144 flows over a topmost layer oftape first. In addition, the tape 120 may extend beyond edges 132 of theflashing 118. Accordingly, the flashing assembly 106 provides awatertight seal when installed and facilitates compliance with anyapplicable regulations for mounting the PV modules 101 (shown in FIG. 1)on the surface 102. Moreover, the flashing assembly 106 reduces theopportunities for installer errors because all necessary components maybe included in the flashing assembly as a single unit (e.g., theflashing 118 and the tape 120).

In some embodiments, additional attachment means such as fasteners 111(shown in FIG. 1) and/or additional tape 120 may be used to secureflashing assembly 106 to the surface 102. The additional attachments mayreduce the stress on the attachment areas 136, 138 of the fastenerassembly. The fasteners 111 may be positioned through the tape 120 suchthat the tape seals the penetrations of the fasteners 111 and preventsliquid flowing along the fasteners. In the example, the fasteners 111are not required and flashing assembly 106 may be secured using onlytape 120.

FIGS. 8-10 show the flashing assembly 106 being attached to the surface102. In this embodiment, a portion of the flashing assembly 106 may bepositioned within an opening or slit 146 in the surface 102. FIG. 8 is aschematic illustration of the surface 102 being prepared to receive theflashing assembly 106. Specifically, the slit 146 is formed using a tool147. In other embodiments, the slit 146 may be formed in any manner andnot necessarily using the tool 147. For example, in some embodiments,the slit 146 may be located at a joint between sections of the surface102 and the overlapping sheets of the sections may be pulled apart toreceive the flashing assembly 106 in the slit 146. In other embodiments,the surface 102 may be prepared in any manner that enables the flashingassembly 106 to function as described. For example, in some embodiments,the surface 102 is cleaned and prepared for attaching to an adhesive.

As shown in FIGS. 9 and 10, the tape 120 may be positioned to facilitatethe flashing assembly 106 being inserted into the slit 146. Wheninserted into the slit 146, the flashing 118 extends at least partiallyunderneath the surface 102. With the flashing 118 in position as shownin FIG. 10, the tape 120 may be positioned over the surface 102 and thesecond attachment area 138 attached to the surface. Accordingly, theflashing assembly 106 is in the second configuration and at least aportion of the surface 102 is positioned between the flashing 118 andthe tape 120. In the second configuration shown in FIG. 10, the tape 120provides a watertight seal between the surface 102 and the flashingassembly 106. In addition, the tape 120 seals the slit 146 and providesan overlap on the surface 102 and the flashing 118. In otherembodiments, the flashing assembly 106 may be installed in any mannerthat enables the flashing assembly to function as described.

In some embodiments, the flashing assembly 106 may include differentconfigurations of the tape 120. For example, FIG. 11 shows the tape 120in a non-overlapping configuration. The tape 120 includes a first strip148, a second strip 150, and a third strip 152. The first strip 148 andthe second strip 150 extend along opposite ends of the edge 132 of theflashing 118. The third strip 152 extends along the edge 132 between thestrips 148, 150. Accordingly, the third strip 152 abuts and forms jointswith the strips 148, 150. Accordingly, the strips 148, 150, 152 mayreduce the material required to assemble the flashing assembly 106. Insome embodiments, the tape 120 includes a single, continuous strip 148.In other embodiments, the tape 120 may include any strips 148, 150, 152that enable the tape to function as described.

In addition, the strips 148, 150, 152 are positioned on the bottomsurface 126 of the flashing 118. The strips 148, 150, 152 are doublesided, i.e., the first attachment area 136 and the second attachmentarea 138 are on opposite sides of the tape. Accordingly, the tape 120 ispositioned between the flashing 118 and the surface 102 (shown inFIG. 1) when the flashing assembly is secured to the surface. In thisembodiment, the tape 120 does not extend beyond the edges 132 of theflashing 118.

FIGS. 12 and 13 show the tape 120 forming angled joints 154. The strips148, 150, 152 are cut along corresponding angles such that the stripsabut and form the angled joints 154. The angle of the joints 154relative to the direction of liquid flow 144 increases the seal of theflashing assembly 106. For example, the flashing assembly 106 may bepositioned such that the joints 154 form an upslope path for the liquidflow 144. In addition, the tape 120 forms a tortuous path for the liquidto inhibit liquid ingress through the flashing assembly 106. In otherembodiments, the tape 120 may be any shape that enables the flashingassembly 106 to function as described.

In the embodiment shown in FIGS. 14 and 15, the tape 120 is shaped tocorrespond to the shape of the edge 132 of the flashing 118.Specifically, the tape 120 includes angled corners that correspond toangled corners of the flashing 118. The tape 120 is positioned on thebottom surface 126 of the flashing 118 and extends along but not beyondedges 132 of the flashing. In other embodiments, the tape 120 may haveany shape that enables the flashing assembly 106 to function asdescribed. For example, in some embodiments, the tape 120 may includecurves. The shape of the tape 120 may allow the tape to include asingle, continuous piece extending along the edge 132 of the flashing118. In addition, the shape of the tape 120 can inhibit waterpenetration at the joints of the tape.

In addition, in this embodiment, the edge 132 includes linear segmentsoriented oblique to each other. Accordingly, the flashing 118 includesangled or chamfered corners. In other embodiments, the flashing 118and/or the tape 120 may have any shape that enables the flashingassembly 106 to function as described. For example, the flashing 118 mayinclude curves.

As shown in FIG. 16, the shape of the tape 120 may facilitate the tape120 being cut to correspond to the shape of the flashing 118 (shown inFIG. 15) with reduced waste. For example, the third strips 152 may becut such that an inner edge 156 and an outer edge 158 of the strips areparallel. Accordingly, a single cut may be made to form the inner edge156 of a strip 152 and the outer edge 158 of an adjacent strip 152. Inother embodiments, the tape 120 may be cut in any manner that enablesthe tape to function as described.

FIG. 17 is a perspective view of an embodiment of a flashing assembly172 for a stanchion 174 (shown in FIG. 23). The flashing assembly 172 issimilar to the flashing assembly 106 (shown in FIG. 2) except theflashing 176 of the flashing assembly 172 is configured to extend aroundthe stanchion 174 (shown in FIG. 22). The tape 120 may be positionableto facilitate positioning the flashing assembly 172 relative to thesurface 102. For example, as shown in FIG. 17, a portion of the tape 120may be displaced to facilitate positioning the flashing 176 along thesurface 102 as in FIG. 8. In other embodiments, the tape 120 may bepositionable in any manner that enables the tape to function asdescribed.

In this embodiment, the second attachment area 138 overlaps the flashing118 and a portion of the second release sheet 142 extends between thesecond attachment area and the flashing. Accordingly, the tape 120 maybe positioned to expose a portion of the flashing 118 and facilitate theflashing being positioned relative to the surface 102 (shown in FIG. 9)and the preparations (e.g., slit 146 (shown in FIG. 9)) in the surface.

FIG. 18 is a perspective view of a package 160 for use with the flashingassembly 106. FIG. 19 is a perspective view of the flashing assembly 106being positioned in the package 160. FIG. 20 is a perspective view ofstacked flashing assemblies 106 in the package 160. The package 160includes a container 162 and a receptacle 164. In this embodiment, thecontainer 162 is rectangular cuboid. In other embodiments, the container162 may have any shape that enables the package to function asdescribed. For example, in some embodiments, the package 160 may becylindrical, spherical, cuboid, prismatic, and/or any other shape.

The container 162 defines an interior space 166 that receives theflashing assembly 106 in a first configuration. Specifically, thecontainer 162 is sized to receive the flashing 118 and the tape 120attached to the flashing. Moreover, the container 162 is sized toreceive a plurality of the flashing assemblies 106. For example, asshown in FIGS. 19 and 20, the flashing assemblies 106 may be arranged ina stacked configuration and positioned within the interior space 166.The second release sheets 142 (shown in FIG. 6) on the flashingassemblies 106 in the first configuration allow the flashing assembliesto be stacked without the second attachment areas (shown in FIG. 6)attaching to adjacent flashing assemblies. In some embodiments, theflashing assemblies 106 may be positioned such that the release sheets140, 142 (shown in FIGS. 3 and 6) are accessible and may be removedwhile the respective flashing assembly is positioned in the interiorspace 166. For example, as shown in FIG. 20, the flashing assemblies 106may be positioned upside down such that the bottom surface 126 and thesecond release sheets 142 (shown in FIG. 6) are accessible. In otherembodiments, the flashing assemblies 106 may be positioned in thecontainer 162 in any manner that enables the package 160 to function asdescribed.

In this embodiment, the receptacle 164 is positioned within the interiorspace 166 and attached to the container 162.

FIGS. 21 and 22 are perspective views of embodiments of a flashingassembly 172 for a stanchion 174 (shown in FIG. 23). The flashingassembly 172 is similar to the flashing assembly 106 (shown in FIG. 2)except the flashing 176 of the flashing assembly 172 is configured toextend around the stanchion 174 (shown in FIG. 23). In the embodimentshown in FIG. 21, the tape 120 includes overlapping strips. In theembodiment shown in FIG. 22, the tape 120 includes a single continuouspiece extending between the flashing 176 and the surface 102.

FIGS. 23-27 show the flashing assembly 172 installed on a roof. Thefirst portion 122 may extend above an upper surface of the roof (e.g.,roof tiles) when the second portion 124 is coupled to a lower surface(e.g., an underlayment). Accordingly, the flashing 176 may direct fluidaway from the base of the stanchion 174.

In some embodiments, a plurality of flashing assemblies 172 are used toflash a single stanchion 174. For example, in the embodiment shown inFIG. 24, an upper flashing assembly 180 is coupled to an upper surface182 and a lower flashing assembly 184 is coupled to a lower surface 186.In other embodiments, any number of flashing assemblies 172 may be usedwith the stanchion 174 that enable the stanchion to function asdescribed.

FIG. 28 is a sectional view of a flashing assembly 172 and a stanchion174. The stanchion 174 may be secured to the surface 102. Duringinstallation, the flashing assembly 172 is positioned over the stanchion174. The flashing assembly 172 may be in the first configuration suchthat the tape 120 is attached to the flashing 176 and allows theflashing 176 to be positioned relative to the stanchion 174. The secondrelease sheets 142 (shown in FIG. 6) may then be removed from theflashing assembly 172 and the tape 120 may be attached to the surface102. In the second configuration, the flashing assembly 172 provides awatertight seal on the surface 102. The tape 120 may include one or morestrips that provide a continuous barrier to water. The stanchion 174 maythen be connected to a support system for the PV module 101 (shown inFIG. 1). Accordingly, the flashing assembly 172 simplifies the mountingof the PV modules and provides a watertight seal for any penetrations.

FIG. 29 is an exploded perspective view of an embodiment of the flashingassembly 172 and the stanchion 174. In this embodiment, the tape 120 ispositioned on the bottom surface 126 and the top surface 128 of theflashing 176. Accordingly, the layers of tape 120 may provide a betterseal and facilitate attaching the flashing assembly 172 to the surface102. In addition, the tape 120 may be positioned between the stanchion174 and the surface 102 and seal any penetrations used to secure thestanchion.

The tape 120 on the top surface 128 extends along and beyond the edges132 of the flashing 176 on all sides. Accordingly, the tape 120 providesa watertight seal around the entire perimeter of the flashing assembly172. As a result, the flashing assembly 172 may be suitable for alow-slope or flat surface 102 where liquid may flow in any direction. Inother embodiments, the flashing assembly 172 may have any configurationthat enables the flashing assembly to function as described. Forexample, in some embodiments, the tape 120 includes a single strip thatextends continuously around the entire perimeter of the flashing 176 asshown in FIG. 38.

In addition, as shown in FIG. 36, the tape 120 may extend across aninterface between the flashing 176 and the post stanchion 174.Accordingly, the tape 120 may be located on at least four differentinterfaces to provide watertight seals and prevent liquid penetratingthe flashing assembly 106. For example, the flashing assembly 172 mayinclude a first tape 120 extending along the interface of the poststanchion 174 and the flashing 176, a second tape 120 extending along atop surface of the flashing and the surface 102 (shown in FIG. 28), athird tape 120 extending between a bottom surface 126 of the flashingand the surface, and a fourth tape 120 extending between a bottomsurface of the post stanchion and the surface. In other embodiments, theflashing assembly 172 may include any tape 120 that enables the flashingassembly to function as described.

In the embodiment shown in FIGS. 29 and 31, the tape 120 is square anddefines a square opening to receive the flashing 176. In otherembodiments, the tape 120 may be any shape that enables the flashingassembly 172 to function as described. For example, in an embodimentshown in FIGS. 30 and 33, the tape 120 defines a circular opening forthe flashing 176. In embodiments shown in FIGS. 35-38, the tape 120 iscircular and defines a circular opening. In further embodiments, thetape 120 may be circular, rectangular, triangular, polygonal, conical,cylindrical, and/or any other shape.

In the embodiment shown in FIG. 33, the tape 120 defines a circularopening that has a diameter less than a diameter of the circular base ofthe first portion 122. As a result, the tape 120 extends at leastpartially along the first portion 122 and may seal an interface betweenthe second portion 124 and the first portion 122. In other embodiments,the tape 120 may extend along any portion of the flashing 176 thatenables the tape 120 to function as described. For example, in someembodiments, the tape 120 may include any number of strips, includingone.

FIG. 34 is a perspective view of an underside of the flashing assembly106 including layers of tape 120. Specifically, a first layer of tape120 is positioned on the top surface 128 of the flashing 118 and asecond layer of tape is positioned on the bottom surface 126 of theflashing. The first layer of tape 120 may be single sided tape and thesecond layer of tape may be double-sided tape. Accordingly, the layersof the tape 120 may provide a watertight seal and a more secureattachment between the flashing assembly 106 and the surface 102 than asingle layer of the tape. In other embodiments, the flashing assembly106 may include any layers of tape 120 that enable the flashing assemblyto function as described.

In the embodiments shown in FIGS. 29-33 and 35-38, a single strip oftape 120 extends continuously around the entire perimeter of theflashing 176. Accordingly, the flashing assembly 172 forms a seamlessseal along the surface 102 (shown in FIG. 28) and around the stanchion174. As a result, the amount of seams are reduced and the risk of wateringress is lessened. Accordingly, the flashing assembly 172 may besuitable for a low-slope or flat surface where liquid may flow inseveral directions. In some embodiments, multiple layers and/oradditional strips of tape 120 may be used in addition to the continuoustape 120 about the perimeter.

In addition, the shape of the flashing 176 and/or the tape 120 maysimplify installation. For example, the circular shapes shown in FIGS.35-38 do not require alignment with features (e.g., joints and corners)of the surface 102 (shown in FIG. 28) and/or with objects on the roofsuch as parapet and rooflines. Also, the shape of the flashing 176and/or the tape 120 may provide a preferred appearance due to thesymmetry and continuous edges of the installed flashing assembly 172.

In reference to FIG. 38, the tape 120 may have a shape that correspondsto the shape of the flashing 176. For example, in this embodiment, theflashing 176 includes a circular second portion 124 and a conical firstportion 122. The first portion 122 has a circular base. The tape 120 iscircular and defines a circular opening to receive the flashing 176. Thetape 120 extends across the second portion 124 and about the firstportion 122. Accordingly, the flashing assembly 172 seals around theentire perimeter of the stanchion 174. In other embodiments, the tape120 and the flashing 176 may have any shapes that enable the flashingassembly 172 to function as described.
